Just like the title states, NOS Carter WGD Carb p/N 3714s still in the box with all gaskets and paperwork as original. Tag on the carb reads: H1 87148. Paperwork in the box states that it fits 265 and 283 Chevrolets from 1955-1963. Don't believe this has ever been mounted but you can look at the pictures and determine for yourself, was bought from an estate along with a bunch of other NOS parts. Paypal accepted and will ship for free anywhere in the Continental US. I can send more pictures as well, let me know if you have any questions. You can contact me through PM but may have better luck emailing me at InterstellarO@gmail.com Thanks!
